Infective stage is the life cycle stage where parasite able to initiate an infection in a definitive or intermediate host.
Diagnostic stage is the life cycle stage leaving the definitive host, it is the stage that links the parasitic way of life with either the free-living phase of the life cycle or the phase of development that occurs in an intermediate host.
Larva
Sporozoite is the infective stage of Maaria.
The infective larval stage of Ascaris lumbricoides, a type of roundworm, is the third-stage larva (L3). This larva develops within the eggs after they are laid and must undergo a process of maturation in the environment, usually in soil, to become infective. Once ingested by a host, the eggs hatch in the intestines, releasing the larvae that can then migrate through the body.

The difference between rhabditiform and filariform larvae of hookworms is as follows: 1. rhabditiform - juvenile stage 1 The larvae grow and molt in the soil, and later transform into a juvenile stage 2. 2. rhabditiform - juvenile stage 2 Juvenile stage 1 molts a second time, then becomes juvenile stage 3. 3. filariform - juvenile stage 3, the infective form The molting and growth process from rhabditiform to filariform usually take 5 to 10 days. Filariform larvae can penetrate human skin, travel through the blood vessels and heart, eventually entering the lungs where they can interfere with breathing and cause other respiratory problems.

The infective stage of Taenia saginata, also known as the beef tapeworm, is the larval form called the cysticercus. This stage is typically found in the muscle tissue of cattle, the intermediate host. When humans ingest raw or undercooked beef containing cysticerci, they can become infected with T. saginata.

No, EPM is not transmitted from horse to horse. EPM is contracted by eating feedstuffs or drinking water that has been contaminated by oppossum feces wich contain S. neurona sporocysts--this is the infective stage of the S. neurona lifecycle. This infective stage is not shed in equine feces.
Generally a woman will have a diagnostic medical sonography between 10 and 13 weeks into the pregnancy. This ultrasound will date the pregnancy and tell if the woman is carrying one baby.
